Abstract

In this paper, a quadruple linear polarization (LP) and circular polarization (CP) diversity antenna with a reconfigurable coupler is presented. The proposed antenna has two linear (vertical and horizontal) and two circular (right-handed and left-handed) polarizations. In order to implement real-time polarization diversity antenna, the electrical switches are used in the proposed antenna feeding network which is four mode reconfigurable coupler. The measured gains and the axial ratios of the proposed antenna are 5.6 ~ 6 dBi and 0.5 ~ 1.5 dB in four operation modes and two CP modes.
